Insights into the role of GPX3, a highly efficient plasma antioxidant, in cancer.

Insights into the role of GPX3, a highly efficient plasma antioxidant, in cancer. Biochem Pharmacol. 2020 Dec 10;:114365 Authors: Nirgude S, Choudhary B Abstract Glutathione peroxidases are well known antioxidant enzymes. They catalyze the reduction of hydrogen peroxide or organic hydroperoxides using glutathione. Among the reported 8 GPxs, GPx3, a highly conserved protein and a major ROS scavenger in plasma, has been well studied and confirmed to play a vital role as a tumor suppressor in most cancers. Additionally, this gene is known to be epigenetically regulated. It is downregulated either by hypermethylation or genomic deletion. In this review, we summarized the role of GPX3 in various cancers, its use as a prognostic biomarker, and a potential target for clinical intervention.
